Laser device capable of making a temperature distribution uniform in a slab-shaped laser medium

摘要: In a laser device for producing beam along first predetermined direction by exciting slab-shaped medium an excitation member, reciprocating motion is carried out second transverse to the and divided into plurality of cycles which have different amplitudes. Both edge zones are excited heated member during selected one while they not remaining cycles. Thus, heat accumulated in diffused dissipated intermittently heating zones. The may be reciprocated relative member. Alternatively, medium.
